: Captchas are in a continual arms race with bot writers, and wax and wane in difficulty as new attacks and counter-measures are deployed. ReCAPTCHA occasionally becomes more lengthy when they refresh their image library; we may be experiencing that. It sure doesn't seem to be slowing down the creation of new phantom usernames -- does registration even have the captcha?

:: Firstly yes, and that might be the problem, because ReCAPCHA is still quite mild on other sites. Whomever is automating username registration here (which has been going on at least five years) may have fallen prey to a new countermeasure increasing their failure rate and making our site's angry.

Re "ium": Shouldn't we try to keep the explanation short and to the point? This comic is about "isotopes", i.e. about different options of how to construct a single atom (or atom-like entity). IMO, there is no need to include many-body effects in a set of multiple electrons ([https://www.explainxkcd.com/wiki/index.php?title=2719%3A_Hydrogen_Isotopes&type=revision&diff=303973&oldid=303971 "Fermi velocity"] or [https://www.explainxkcd.com/wiki/index.php?title=2719:_Hydrogen_Isotopes&oldid=304060 "electron degeneracy pressure"]); just as there is no need to discuss, say, the kinetic theory of gases made up of these isotopes, or how they would be able to form fluids or solids. It is good to see that people who contribute here know about these effects, but I think that the explanation does not benefit from extending the discussion too far beyond the subject of a given comic. If anything, it might be worthwhile to include a reference to {{w|ion trap|ion traps}} - especially since in a Penning trap electrons actually go in circulating orbits (although not exactly circular). --[[Special:Contributions/172.70.246.210|172.70.246.210]] 11:56, 4 January 2023 (UTC) | Re "ium": Shouldn't we try to keep the explanation short and to the point?
